摘要
论述了用ＤＧＰＳ／ＳＩＮＳ／ＲＡ组合导航系统引导的某无人机自动着陆系统的总体方案，利用该无人机的小扰动线性化方程，对其轨迹控制系统进行了分析设计。在不采用速度控制系统的情况下，利用该无人机的全量微分方程，对其在各种起始状态及各种干扰下的自动着陆过程进行了仿真。仿真结果表明，着陆性能符合要求。
Deals with the analysis and research on the automatic landing system of a pilotless aircraft. After describing the overall plan for the automatic landing system of the pilotless aircraft with DGPS/SINS/RA combination guidance and trajectory control, the system is analyzed and designed by means of small disturbance equations of the pilotless aircraft. With non linear equations of the pilotless aircraft and different initial state as well as various disturbances, the automatic landing process is simulated without speed control. Simulation results show that the requirement of landing characteristic can fully be met.
